ing is a specification.

This invention relates to improvements in rotary duplicating machines.

It consists essentially in providing means in such machines whereby in addition to the matter printedby the machine (whether directly from type bytype through a ribbon or by a wax or other stencil) other matter can be printed at the same operation, either'from a block, metal, rubber, or other type or anelectro-type separately. inked.

This invention will be fully described with reference to the accompanying drawings.

the printing is effected through a ribbon A bytype set up on a rotary cylinder B (or upon a segmental drum on flexible form carried bya rotary cylinder). The additional matter to be printed is formed on an electro-type plate C fitted with proje'c- I tions 0 to engage in the type slots 6 of the cylinder B (or segmental drum or form). One side or edge of the additional'printing plate C is fitted with an inclinedor cam surface C which engages a runner (Z controlling an inking device D. The inking device is pivotally mounted on a bar (5 carried on supports E. affixed to'the frame of the machine so that the engage- Inent of the cam surface C wvith the runner (Z causes the-inking device to be depressed and the rollers (Z thereof to engage the printing surface of. the additional printing plate 0 to apply the inkto the printing surface of the latter, at each revolution thereof. A spring (i aflixed to a projection (1* on the inking device D and to'the frame of the machine returns the inking device to its normal position when the cam surface has moved out of engagement with the runner (Z.

The additional printing plate C may project almost to the edge of the ribbon A as shown in Fig. 1, or over the edge ofthe ribbon as shown in Fig. 2. I

Instead of an electr'o-type, loose type can be employed, fitted into aplate affixedto the. cylinder, segmental drum or flexible form, and provided with a cam orinclined surface to be engaged by the runner actuating the inking mechanism. The cam surface for actuating the runner of the inking device may be separated from the additional printing plate instead of being formed therewith or affixed thereto and if desired'theinking rollers may be geared together and also positively driven from the rotating cylinder or other rotating part of the machine. m

The electro-type plate C (or the plate carrying the loose type) is fitted over the inking ribbon A, which is free to slide between the plate and the type carried on the cylinder, segmental drum or flexible form.

The electro-type plate A or the plate carrying the loose type can be arranged in any position on the cylinder, segmental drum or flexible form without adjustment or alteration of the position of the inking a plate carrying loose type in slots) is,

as before described with reference to .Figs. 1 to 6, provided with a cam surface C to engage a runner cl controlling an inking device D.

Theinkingdevice Dis pivotally mounted on supports E aflixed to the frame of the machine so that the engagement of the cam surface C with the runner d causes the inking deviceto be depressed and the rollers d thereof to engage the printing surface of the additional printing plate G to appiy the ink to the printing surface of the latter.

A spring d iaflixed to a projection cl on the inking device D and to the frame of the machine returns the inking device to its normal position when the cam surface has moved out of, engagement with the runner d. I The printing plate C is provided with pinse whichengage in holes in the side of vth'ecylinder B and if desired, with a spring e (see Figs. 8 to 10) to hold it firmly in position but at the samejtime allowing its position to be readily altered.

The cam surface for actuating the runner of the inking device may be separated from the additional printing plate instead of being formed therewith or afiixed thereto, and if desired the inking rollers may be geared together and also positively driven from the rotating cylinder or other rotating part of .the machine. Instead of the inking device having two rubber rollers as shown in the drawings, a single roller, felt covered or otherwise, may be employed.

The additional printing plate shown in Figs. 12 and 13 is formed of metal with rubber'type afiixed thereto, and is fitted on to the cylinder over a packing strip F.

The additional plate can be arranged in :any position on the cylinderin relation to the stencil E without adjustmentor alteration of the position of the inking mechanism as the latter is actuated by the position of the cam surface whichis moved with the printng plat o I n the case of a duplicatitng machine with a .wax stencil the rubber or other type may stand out sufficiently from the stencil to be inked by the inking roller or rollers without the necessity of a cam for bringing the lat- 'ter into contact with the printing surface.

By this invention it is possible to printheadings on letter paper or the like at the same time as, and in .a differentcolour to, the body of the duplicated letter; Itis also possible to print a signature or one .or more lines in the body of the letter in a different ink and or type from the rest of the letter.

\Vhat I claim as my inventionand desire to protect by Letters Patent is 1. In a rotary duplicating machine the combination with the main duplicating cylinder of a separately inked auxiliary printing device, means for holding said device in any position on the main cylinder so that the auxiliary matter printed can occupyany position desired in relation to the body ofthe matter-printed, a separate'inking mechanism for the auxiliary printing device and a cam surface movable with said auxiliary printing device mechanism. 7 1 I I 1 2. In a rotary duplicating machine the combination with the main duplicating cylinder of an auxiliary printing plate, projections on'the said plate to engage apertures.

to trip the separateinking I on the main cylinder to hold the plate inany positionthereon, a cam aflixed to the plate and a separate inking mechanism adaptedto be operated by said cam. I j

3.1m a rotary duplicating machinethe combination with the main duplicatin'gcylinder of an auxiliary printing plate',"p'rojections on the'underside of said plaixte t'o engage between'the types of the main cylinder to hold the plate in any position thereon, a cam affixed to the plate and a separate 1 inking mechanism adapted to be operated by same cam.

In testimony whereof I have hereunto set my hand in presence of two subscribingwit- I nesses.
